Description

Starting device for vehicle in case of emergency

The present invention relates to an emergency start device for a vehicle, and more particularly, in a vehicle equipped with an immobilizer function, receiving a driving signal of a transponder included in a fob key when an emergency start is implemented according to a system failure or a battery discharge of a fob key. The present invention relates to an emergency start device for a vehicle provided with a power coil switch of a vehicle and an antenna coil capable of amplifying the driving signal and transmitting the amplified driving signal to a system for starting an engine.

Recently, mounting of an immobilizer system, which is a vehicle anti-theft system associated with a ignition key, has become common in preparation for vehicle theft.

As is known, an immobilizer system is a system that generates an encryption code wirelessly from a fob key as a starter key and permits start-up only when the engine ECU (Engine Control Unit) confirms and matches a previously stored ID.

That is, when the driver inserts the portable device fob key into the keyhole and starts it (IG ON), the smart ECU reads the unique ID stored in the fob key, and the unique ID read from the unique fob key and stored in advance. The engine ECU is only allowed to start if it compares and confirms that it is a normal registration fob key.If it is not the original genuine fob key of the vehicle, the engine injection is blocked by blocking fuel injection and ignition control. Do not get caught.

The fob key used in such an immobilizer system includes a transponder for storing an anti-theft related security program and an ID code and generating an encryption code.

The transponder is driven by electromagnetic forces derived from the antenna coils installed around the key cylinders, which generate cryptographic codes by the electromagnetic energy from the antenna coils when the fob key is IG ON after keyhole insertion. This encryption code is wirelessly transmitted to the antenna coil.

Transponder data wirelessly transmitted from the antenna coil is converted into data that can be used by the smart ECU in the antenna coil assembly and transferred to the smart ECU, which reads the data and controls engine starting accordingly.

Recently, due to the development of the immobilizer system, the wireless ID code signal generated from the fob key is transmitted to the vehicle while the driver carries the fob key in the pocket of the garment without the need to insert the fob key into the key holder. The 'smart ignition' device that makes the engine of the vehicle startable by using the vehicle is widely used.

At this time, the fob key is provided with an antenna for near field communication and a power supply unit for supplying current to the antenna, that is, a battery and / or a transponder.

Here, the transponder is to approach the transponder of the fob key around the antenna coil provided separately from the antenna coil in case of emergency that can not communicate with the vehicle by using the antenna due to the battery discharge of the fob key or the immobilizer system. It is for operating the vehicle engine by induced electromagnetic force.

Therefore, the inside of the vehicle is provided with a slot formed with an antenna coil for operating the engine according to the approach of the fob key transponder in case of an emergency in which the discharge of the fob key battery or the immobilizer system.

At this time, the slot is composed of a holding device for holding a fob key, an antenna coil for outputting a transponder driving signal, and / or a head amplifier for amplifying a signal output from the antenna coil.

However, although the slot is not used for everyday use only in an emergency, such as when the battery of the fob key is exhausted, it is necessary to secure a mounting space on one side of the vehicle to provide the slot.

However, computerization of a vehicle system is rapidly progressing in recent years, and more functions are required, which increases the number of electronic components mounted in a vehicle, thereby making it very difficult to secure a sufficient space for mounting a forb key in a limited space of the vehicle. have.

The present invention reduces the mounting space of the antenna coil and head amplifier and the like to communicate with the transponder of the fob key, and to reduce the manufacturing cost by installing a circuit for performing the head amplifier function on the printed circuit board of another switch device There is a problem to solve.
